I ordered this pipe cutter here from MF and used it to cut one of my rack tubes and let me tell you: it's not the best, but it gets the job done. This pipe cutter's not made to cut industrial-grade steel, so if you own a Gibraltar rack and need to shorten your tubes, this pipe cutter is for you. It's hard to use at first, but you get used to it. There's also a replacement blade inside the blade. There is a GibraltarDIY video on YouTube describing the pipe cutter and how it works.
